Rex Grossman's season is over after spraining a ligament his left knee. Now the quarterback of the Chicago Bears has an uncertain future with his contract expiring. Grossman, who overcame major injuries early in his career, said there is no structural damage this time to his knee. He was hurt last Thursday in the Bears' loss at Washington. Now, after an erratic season that saw him losing his starting job to Brian Griese after the first three games and then getting it back, he doesn't know what will happen once the season ends. "I'd like to be back here if I'm wanted back here," said Grossman, who endured heavy criticism last season despite helping the Bears make the Super Bowl. "We'll see what goes on." The Bears are 5-8 and out of the playoff picture. Grossman, a first-round pick in 2003, said he wants to be somewhere where he can compete for the starting job.
